Filament Rack

This is a rack to stop the piles of filaments spools from making a mess of your workspace.
It uses a 3/4-inch in diameter by 48" dowel rod, and I am using 6 20-pound drywall anchors to hold it up.
It should hold 8 spools of filament.
If you want to mess with the design, here's my Tinkercad file: https://www.tinkercad.com/things/4hZgSiLMMU5-filament-rack?sharecode=zQyRuOyEEpXofPtkVq87T3yHegbZvZ8dZwYb1qZn7-E
